Processing of banded magnetite quartzite (BMQ) ore using ...

Apr 01, 2014 · Banded magnetite quartzite (BMQ) ore occurs as separate veins in iron ore mines and recovered while mining the natural hematite ore. In India, such ores are considered as low grade iron ores with Fe content of 25–45%, SiO 2 30–60% and Al 2 O 3 1–5%. No commercial plant has been set up so far to recover the iron values from such ores for ...

Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe3O4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, which is how ancient peoples first discovered the property of magnetism.

Dec 16, 2010 · To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts.

Banded iron formation - Wikipedia

A typical banded iron formation consists of repeated, thin layers (a few millimeters to a few centimeters in thickness) of silver to black iron oxides, either magnetite (Fe 3 O 4) or hematite (Fe 2 O 3), alternating with bands of iron-poor chert, often red in color, of similar thickness. A single banded iron formation can be up to several hundred meters in thickness and extend laterally for ...
